Many thanks for the response, @eblake:

Just tried it - but unfortunately, the same error occurs; here is a pastebin of the log output of the autogen/configure and make steps:

Though, it is interesting that around the line "config.status: executing depfiles commands", here there are four `0 [main] generator 16821 dofork: child -1 - forked process XXXX died unexpectedly` messages, whereas in the git build I've always used to get only one. Still, that breaks the `make` part ...

Any other suggestions? Thanks!
